Nicholas sent a chain letter to his friends, asking them to forward the letter to more friends. Every 12 weeks, the number of pe

ople who receive the email increases by an additional 99%, percent, and can be modeled by a function, P, which depends on the amount of time, t (in weeks). Nicholas initially sent the chain letter to 50 friends.

Answer:

P(t)=50(1.99)^{t/12}

Step-by-step explanation:

The problem can be modeled by using the compound growth formula.

Given, Initial number P_0 of people who Nicholas sent the chain letter t=50

The growth rate, r =99%=0.99

Period of Growth,k =12 Weeks

P(t)=P_0(1+r)^{t/k}

Therefore, in any week (t) after Nicholas initially sent the mail, the number of people who receive the email is modeled by the function:

P(t)=50(1+0.99)^{t/12}\\\\P(t)=50(1.99)^{t/12}

What is the surface area of this figure?
disa [49]

Answer:

72 sq. mi

Step-by-step explanation:

Breaking this down, we have 2 right triangles with sides of 3, 4, and 5 miles, and 3 rectangles with dimensions 3 x 5, 4 x 5, and 5 x 5 miles. Remember that the area of a triangle is 1/2 x b x h , where b and h are the triangle's base and height. The base and height of the triangles at the bases of the figure are 3 and 4, so each triangle has an area of 1/2 x 3 x 4 = 1/2 x 12 = 6 sq. mi, or 6 + 6 = 12 sq. mi together.

Onto the rectangles, we can find their area by multiplying their length by their width. Since the width of these rectangles is the same for all three - 5 mi - we can make our lives a little easier and just "glue" the lengths together, giving us a longer rectangle with a length of 3 + 4 + 5 = 12 mi. Multiplying the two, we find the area of the rectangles to be 5 x 12 = 60 sq. mi.

Adding this area to the triangle's area gives us a total area of 12 + 60 = 72 sq. mi.

d1i1m1o1n [39]

Answer: A.4Runner cost more for $11.02

              B.Cost of fuel for Elentra: 3.75*3.59=$13.46

                 Cost of fuel for 4Runner : 6.818*3.59=$24.48

Step-by-step explanation:

A.Find how many gallons 4Runner spends on 150 mile trip.

use proportion

22:1=150:x

22x=150

x=150/22

x=6.818 gallons  

Cost of fuel for 4Runner : 6.818*3.59=$24.48

Calculation for Elentra:

40:1=150:x

40x=150

x=150/40

x=3.75 gallons

Cost of fuel for Elentra: 3.75*3.59=$13.46

Cost of fule for 4Runner-Cost of fuel for Elentra=24.48-13.46=$11.02

4Runner cost more for $11.02

B.Cost of fuel for Elentra: 3.75*3.59=$13.46

Cost of fuel for 4Runner : 6.818*3.59=$24.48
